Alfuzosin 2025 Price & Uses: Comprehensive Guide on Dosage, Side Effects, and Interactions

Discover everything about Alfuzosin, a leading medication for benign prostatic hyperplasia (BPH). Learn about its benefits, dosage guidelines, potential side effects, warnings, drug interactions, and availability in 2025.

Key Facts About Alfuzosin

  1. Available as both a generic medication and under the brand name Uroxatral.
  2. Comes exclusively in an extended-release oral tablet form for consistent therapeutic effects.
  3. Primarily prescribed to adult men for treating benign prostatic hyperplasia (BPH), helping to relax prostate and bladder muscles to ease urinary symptoms.

Critical Safety Information

  • Blood Pressure Alert: Alfuzosin can cause sudden drops in blood pressure, especially when moving from sitting or lying down to standing. This may lead to dizziness or fainting. Avoid driving or operating heavy machinery until you understand how the medication affects you. If dizziness occurs, lie down with legs elevated and consult your healthcare provider if symptoms persist.
  • Heart-Related Warning: Serious heart side effects, including worsening chest pain or angina, may occur. If you experience sharp or squeezing chest pain, pain radiating to arms, neck, or back, difficulty breathing, sweating, dizziness, or nausea, seek immediate medical attention and discontinue alfuzosin.

What is Alfuzosin?

Alfuzosin is a prescription alpha-blocker medication available as an extended-release oral tablet. It is marketed under the brand name Uroxatral and also available as a more affordable generic option. Generic versions may vary in availability depending on strength and form.

Purpose and Mechanism

Alfuzosin treats benign prostatic hyperplasia (BPH), commonly known as an enlarged prostate, by relaxing smooth muscles in the prostate and bladder. This action improves urine flow and reduces BPH symptoms.

It specifically targets alpha-1 receptors in these areas, minimizing urinary obstruction without affecting other body systems.

Potential Side Effects

While Alfuzosin does not typically cause drowsiness, it may lead to other side effects.

Common Side Effects

  • Dizziness
  • Headache
  • Fatigue or tiredness

These mild symptoms often resolve within days to weeks. Consult your doctor if they worsen or persist.

Serious Side Effects

Seek immediate medical help if you experience:

  • Severe blood pressure drops causing fainting or loss of consciousness
  • Prolonged erections (priapism) lasting more than 4 hours, which can cause permanent damage if untreated

Note: This information is not exhaustive. Always discuss side effects with your healthcare provider.

Drug Interactions to Consider

Alfuzosin can interact with various medications, potentially altering its effectiveness or increasing side effects. Inform your doctor about all drugs, supplements, and herbs you use.

Medications to Avoid or Use with Caution

  • Other Alpha-Blockers: Such as doxazosin, prazosin, silodosin, tamsulosin, and terazosin, which may amplify side effects.
  • Blood Pressure Medications: Including ACE inhibitors (e.g., lisinopril), ARBs (e.g., losartan), beta-blockers (e.g., metoprolol), calcium channel blockers (e.g., amlodipine), diuretics, vasodilators, and nitrates, which can increase risk of hypotension.
  • Erectile Dysfunction Drugs: PDE-5 inhibitors like sildenafil and tadalafil may cause dangerously low blood pressure when combined with alfuzosin.
  • CYP3A4 Enzyme Inhibitors: Such as ketoconazole, itraconazole, and ritonavir, which may elevate alfuzosin levels and side effects.

Always consult your healthcare provider before combining medications.

Important Precautions

Allergy Risks

Severe allergic reactions, including difficulty breathing, swelling of the face or throat, rash, or fever, require emergency medical attention. Do not use alfuzosin again if you have had an allergic reaction to it.

Special Populations

  • Liver Impairment: Avoid use in moderate to severe liver disease due to increased drug accumulation.
  • Kidney Problems: Use cautiously in severe kidney impairment.
  • Heart Conditions: Use with caution if you have QT prolongation or are taking QT-prolonging drugs.
  • Prostate Cancer Screening: Because BPH and prostate cancer share symptoms, your doctor will perform necessary tests before prescribing alfuzosin.
  • Cataract Surgery Patients: Inform your eye surgeon if you are taking or have taken alfuzosin to reduce risk of intraoperative floppy iris syndrome.
  • Pregnancy and Breastfeeding: Not indicated for women; safety not established.
  • Older Adults: May have increased risk of side effects due to slower drug clearance.
  • Children: Not recommended for use.

How to Use Alfuzosin

Dosage depends on age, medical condition, and response to treatment. Follow your healthcare provider’s instructions carefully.

  • Store medication at room temperature (59°F–86°F), away from moisture and light.
